As with other measures of coherence and entanglement, the coherence of assistance and the entanglement of assistance are also closely related. In fact, the relative entropy coherence of assistance is equal to the entanglement formation of assistance [1]}, [2]}, [3]}, [4]} and the \(l_1\)  norm coherence of assistance corresponds to the convex-roof extended negativity entanglement of assistance [5]}, [6]}, [7]}.
As intrinsic characteristics of quantum physics, the inextricable relationship between quantum coherence and quantum entanglement is not limited to specific quantum coherence measures and entanglement measures as well as the coherence of assistance and the entanglement of assistance. Ref. [8]} shows any coherence can be converted to entanglement via incoherent operations, and each entanglement measure corresponds to a coherence measure. It has been further shown that coherence can be converted to bipartite nonlocality, genuine tripartite entanglement and genuine tripartite nonlocality [9]}.
In Refs. [10]}, [11]} the authors construct an entanglement monotone based on any given coherence measure. More generally, Ref. [12]} establishes a general operational one-to-one mapping between coherence measures and entanglement measures.
